Two boarding schools sit on either side of a lake. At times they are against each other, at times they work together. That's the way it's always been with the boys from Shiverstone Castle and the girls from Rose Cliffs.
When the Shiverstone Knights sneak out on a night-time mission to Rose Cliffs Castle, they're ready for war. The knights don't faze the Rose Cliffs girls though: prank for prank, they match the boys. Only a final battle at the lake will show who is the best prankster of all!
